Vehicle energy conservation indicating device and process for use

In combination a vehicle fuel economy indicating device for indicating miles per gallon or the equivalent, a drive means operated by a fuel consumed measuring means, a connection to an odometer drive means, the improvement comprising two oppositely disposed cooperable measuring means, an alignment member operatively connected to each of said cooperable measuring means, said operative connection providing pivotal mounting means between said cooperable measuring means and said alignment member, said operative connection providing independent linear translation movement to each of the oppositely disposed pivotal mounting means, calibrated graphic display scales embodied on the face surface of said device, said face surface juxtapositioned above and parallel to said cooperable measuring means, a first and second scale oppositely disposed and functionally located with respect to each said measuring means, said first scale calibrated for distance traveled and said second scale calibrated for fuel consumed, a third scale diagonally disposed between said first and second scales and calibrated to read average miles per gallon or the equivalent, observation means provided on said face surface adjacent to said scales thereby allowing simultaneous viewing of the registrations with said scales, the consequential operation of said oppositely disposed cooperable measuring means together with said alignment member all relative to said calibrated scales according to a mathematical relationship for vehicle fuel economy thereby indicating the miles per gallon at any related trip distance and fuel consumed setting.
